I wouldn't say that, CSS 2 support isn't really the issue. Modifying
stylesheets is a bit of a chore but it's well supported (at least by
browsers that Prototype.js supports) and once you have a function to
do it... :-)
The link below shows a specific example, the general idea is to sift
through the style sheets looking for the appropriate rule, then modify
it. It's easy if you're looking for a class or ID, tougher for pseudo-
classes and other rule types.

If you have lots of individual elements to hide (say a column in a
table) it is much, much faster to modify a class rule that they all
share than loop over all the rows and hide cells[x] one by one.
